The problem of diagnostics of electronics and plasma units

This is to propose a method for determining the heterogeneity emission based on the analysis of Schottky plot of saturation. It is shown that the problem of determining the emission heterogeneity is ill-posed problems and requires for its solution some prior information about the nature of the solution. Since the current emission equation is described by the Fredholm-1st kind of convolution type, the solution of the inverse problem described by the Tikhonov functional, whose solution for a fixed regularization parameter can be found in closed form by Fourier transformation.
